Pie Chart Data Structure Explanation¶

// Below is a pie chart data demo (divided into 3 sections)
  {
    series: [
      {
        values: [[null, 1.33635905]],
        columns: ['time', 'pieA'],
      },
      {
        values: [[null, 1.79202423]],
        columns: ['time', 'pieB'],
      },
      {
        values: [[null, 2]],
        columns: ['time', 'pieC'],
      },
    ],
  },

Field Description:

Parameter	Type	Required	Description
series	list	Required	Data groups, the length represents how many sections the pie chart is divided into.
series[#]	dict		A set of data representing one section of the pie chart.
series[#].columns	list	Required	The first item in the pie chart is always the field `time`, the second item is the section name ['time', 'section name'].
series[#].values	list	Required	Two-dimensional array; in a pie chart, there should only be one data entry, and if multiple entries exist, only the first one is used.
series[#].values[#]	list		Consists of `[time value, data value]`. In the pie chart, the first value can be set to null, while the second value is the data value (this value serves as the reference for the pie chart's proportion).
